T all whom it may-concern:

ninin of ozone may be forined troni a given L quantity or volunie ot oxygen.

Prior to my invention l ani aware that ozone has been formed by passing an electric current through a wi re wound 'spirally about a glass tube or rod located in a larger tube,

throughv which the oxygen is passed. ,Vith an apparatus such as described the quantity of ozoneproduced or obtained from a given quantity or Volume of oxygen is substantially Small, owing to the fact that the resistance otfered to the passage ot the continuous electriccurrent is substantially nothing, the current, which is of substantially highpotential, Jumping from onecoil of the Wire to another,

so that it passes through the outer tube in substantially a straight path. Y

In accordance with my inyention the electric conductor, preferably rplatinum Wire, is passed, as herein shown, through/a hollow carrier, preferably a glass tube/bent or coiled to extend longitudinally the length/ ofi the ozonizing-charnber (shown as a tube through which the oxygen is passed, the loops of-wire .being independently insulated from each l other, whereby the current, is caused to pass through the entire length of the platinum Wire and is prevented from jumping or short` circuiting.

My' invention therefore consists; essentially, in an apparatus for the production of ozone, of the combi-nation, with an ozonizing-chamber, of the herein-described continuous electric conductor bent or coiled to extend longitudinally the length of the said chamber two or more times to forni through the said chaniber a coniplete continuous circuit of substantially high resistance, the said coils being insulated fronrone anot-her, substantiallyas will be described! Figure l is 'an isometric View of a table or Stand su pporling `an apparatus embodying my invention; Fig. 2, a longitudinal sect-ion of the outer chamber or tube and 'the form of c arrier preferred by me; Fig. 3, a cross-section of N,.Fig. carrier shown in Fig. 2; Fig. 5, a longitudinal section of the outer chamber and a modified form of carrieiyand Fig. 6ta crossfsection of Fig. 5 on line y fy. y l

The gasometer A, containing the supply of oxygen, the induction-coil A', and battery A2., connected to the primary coil thereof by wires A3 A4,'are and may be of any desired or usual or well-known construction.

The gasolneter A is connected by lapret'erably `flexible pip'e, provided iiiit-h a cock, a, to the ozonizing-chamber b',v herein shown as a glass tube of considerable area in cross-section, the oxygen from the gasorneter passing through the ozoni-zing-chamber. The oxygen on its passage through the chamber b is converted into ozone by an electric current or discharge passing through an electric conductor, b2, preferably platinum wire, having one end connected, as' shown, to a bindingpost b3, and its other end joined to a bindingpost, b", the said binding-posts being preferably sealed in the tube b and connected respectively by wiresl'b5 h6 to opposite ends of -thesecondaiy coil of the induction-coil A'.

Tovobtain within a chamber or tnbeb' of substantially small size, ar Substantially large surface or amount of platinum or other Wire,

Vthe latter is preferably inserted through a single glass tube c, which is then bent or coiled,- 'substantially as shown in Fig. 4, and the coils of the tube are then grouped together to enable lthein to be inserted into the chamber b', one end of the latter being then drawn ou t to enable the pipe d to be tted thereon. It vwill thusv be. Seen that a substantially largeaniou nt of platinum Wire is located in the chamber. h', and `the separate-coils are perfectly insulated iroin one another, whereby it is 1np 4'ble fer the current or discharge "togshort--, rcu't' on its passage through thejchainber L .,soilmt the oxygen passed through the said 4 chamber is 2 on linejm Fig. 4, a detail of the IOO ..2 A i, seneca subjected to the maximum elfectof'thc electric current, and thereby a maximum Volume or yield of. ozone vis obtained from a given Volume of oxygen.

I prefer to make the carrier of a single glass tube bent or coiled, as shown in Fig. 4, and grouped as shown in Figs. 2 and 3'; but instead thereof the carrier may bev composed ot' a number of separate tubes grouped togother and bound, as by platinum wires fl', as vshown in Figs. 5 andG.

' lily improved apparatus, While especially designed for Converting' pure oxygen into ozone for medical purposes, may be employed equally as Well for forming ozone from air.

l have herein mentionedplatinum Wire as the electric conductor; but instead thereof I may yemploy any yother suitable conductor which Will not form.with. ozone an injuri ous gasLas, for instance, selenium and alu?` minium. o

l. In anl apparatus for the production of ozone, the combination, with l an ozonizingchamber, b', of the herein-described continuous electric conductor bent or coiled to eX- I tend longitudinally the length of the said chamber two or more times to form through the said chamber a complete continuous circuit of substantially high resistance, the said coils being insulated from one another, substantially as and for the purpose specified.

2. In van apparatus for the production of ozone, a gasomcter to. contain oxygen, an czonizing-chamber, b', connected thereto, the herein descri ned continuous electric conductor or Wire and carrier therefor located in said chamber and composed of coils or tubes of glass or non-conducting material, through which the said continuous Wire is passed, combined With an induction-coil connected to the opposite ends of the said electric conductor, and a current-generator connected to said induction-coil, substantially as described.

in testimony whereof l have signed my name to this speeication in the presence of two subscribing Witnesses. I
